The two numbers differ by about 9 orders of magnitude, so the value of the difference between the larger and the smaller is essentially the value of the larger number. The smaller one, by comparison, can be considered to be zero (for subtraction purposes).
Answer:
The value of a function is the actual calculation done at a certain point. The limit is - roughly speaking - the value at points that are “arbitrarily close” to the same point. For most commonly used functions, the value of a function at a point, and the limit at the same point, is the same - at least for most values.
Find the total amount of socks, 10+12+3= 25 socks. Since Mason only wants to pick a brown pair, he has a chance of 3(brown socks) out of 25 (total socks). Convert 3/25 to a percentage. Multiply 3x4=12
————- So you get 12%, or B
3x4 =100
